IDZSwiftCommonCrypto

A Swift wrapper for Apple's CommonCrypto library.

Using IDZSwiftCommonCrypto

Since CommonCrypto is not a standalone module, you need to generate a fake module map to convince Xcode into allowing you to import CommonCrypto. The GenerateCommonCryptoModule script provides two methods for doing this. Which method you choose depends on whether you want to able to use CommonCrypto and, by extension, IDZSwiftCommonCrypto in playgrounds.

To make CommonCrypto available to frameworks and playground use the command:

    ./GenerateCommonCryptoModule iphonesimulator8.0

This command creates a CommonCrypto.framework in the SDK system library directory. You should now be able to use either CommonCrypto or IDZSwiftCommonCrypto in a playground simply importing them or in your own app project by dragging the IDZSwiftCommonCrypto.xcodeproj into your project.

If you do not want to add any files to your SDK you can use the command

    ./GenerateCommonCryptoModule iphonesimulator8.0 .

This method creates a CommonCrypto directory within the IDZSwiftCommonCrypto source tree, so the SDK directories are not altered, but the module is not available in playgrounds. To use the framework in your own project drag the IDZSwiftCommonCrypto.xcodeproj into your project and set the Module Import Path to the directory containing the CommonCrypto directory created by the script.
